X11 display issues

[Wendy Palm]

along these lines, please add this patch to define a new define for all the
systems who don't allow unix sockets (and some defines i need for the cray port
anyway) (thanks to bill for writing them & sending them to me in the first
place).  i've got more patches for cray, but will send them slowly to make sure
we don't break too much all at once (and please let me know if i send things
incorrectly.)
